Red alert. When the helmeted woodpecker is excited, its bushy, rounded red crest flares out in a magnificent crescent; When the bird is calm, the crest remains at rest in a folded red triangle. One of the world's rarest and lest-known woodpeckers, it is also among the most silent, drumming and calling for a few minutes in the first hour after sunrise. foraging makes little noise as it probes bark fissures and pecks in soft, rotted trees. But the trees it needs are extremely scarce as the Atlantic forest disappears and less than 1% of what remains is old-growth forest. For the woodpecker, there is much cause for alarm.
